The New DEX Pairs stream provides real-time updates when new liquidity pairs are created on decentralized exchanges (DEXes). This documentation follows our standard streaming API structure.

Credit Cost

TBD

Supported Chains

  • Base Mainnet
  • BSC Mainnet
  • Ethereum Mainnet

Supported DEXes

  • Uniswap V2, V3, V4
  • PancakeSwap
This stream is currently in Beta. It is stable for testing and evaluation but may undergo changes in schema or behavior as we continue to improve it. No API credits are currently charged.We welcome your feedback so please reach out to us directly to report issues or request features.
